Hi, At http://c6000.spectrumdigital.com/davincievm/revd/ under Davinci EVM software resources section, there is a zip containing .outs for testing various board components such as aic33, nor, nand flash etc. Do you have idea where to get source code for these utilities ? The sources will be very useful to understand the interfaces and make necessary modifications for a custom board

I am confuse that why Wintech just use only 64MB DDR memory on the DVEVM board? As we know that the DDR memory isn't expensive at all now. As all the software pakages release withe the DVEVM are set to map the 256MB DDR, it will be very difficult for as to use the board with 64MB DDR memory! Thanks again and with my best wishes to you! Beny ¡¡¡¡ Zhang, It seems there is no simple way to change the memory map, because the DSP executable need a fix memory map, so when you changed your memory map you will rebuild all things related to DSP, such as dsp link, codec engine. you can following this link:http://www.mail-archive.com/[email protected]/msg01238.html Thanks George Gu (Xiangyu Gu) Wintech Digital System Co.

And now I have correctly build the examples of the codec engine. Before I run the examples I want to make clearly of this question: We know from TI that the DVEVM board should have 256MB DDR Memory, but the DVEVM board I boughth from Wintech(the dealer of TI in China) has only 64MB DDR Meomory on the board! Now, how can I set the memory map of the Davinci to run the exanples? Since the rules of setting the memory map is so complex in the build_instructions.html file. It is there any easy way to do this? Best Regards! Beny 1. If you _just_ want to rebuild the ARM-side examples, you can comment out C64P and Linux86 from the Build.targets array. What are these targets? * C64P == the "DSP side of DaVinci" target. It's one of TI's DSP processor families (http://focus.ti.com/dsp/docs/dspplatformscontenttp.tsp?sectionId=2&familyId=132&tabId=489). * MVArm9 == "MontaVista Arm 9" target. This is the ARM side of DaVinci. * Linux86 == "Intel's x86" target. A not-always-understood detail about Codec Engine is that it can run "natively" on x86 processors. This feature's got some limitations (codecs must be "local", and must not access hardware since they run in user mode), but you can do a fair amount of development on this environment. 2 & 3. As you correctly supposed, BIOS is only needed if you're building DSP-side content (same with FC - Framework Components). You should set "REQUIRE_BIOS = 0". BUT... Looks like you've identified a bug in xdcpaths.mak where it's always verifying your FC_INSTALL_DIR, even if you're only building for the ARM. Bummer. In your case, since you don't have (or need!) a valid FC installation, you can safely comment out the $(error ...) statement in xdcpaths.mak: ----------------------------------- ifeq ($(wildcard $(FC_INSTALL_DIR)/packages/ti/sdo/fc/dskt2/package.xdc),) #$(error FC_INSTALL_DIR is set to "$(FC_INSTALL_DIR)", which is invalid. Set this in <codec engine examples>/xdcpaths.mak! See the build documentation to correct this error.) endif ----------------------------------- As well as the assignment of MISC_PACKAGES to include $(FC_INSTALL_DIR)/packages at the very end: ----------------------------------- MISC_PACKAGES = $(XDAIS_INSTALL_DIR)/packages;$(DSPLINK_INSTALL_DIR)/packages;$(CMEM_INSTALL_DIR)/packages/;$(FC_INSTALL_DIR)/packages ----------------------------------- We'll fix this in a future CE release. Thanks for flagging this, and let me know if you have any other questions/issues.
